You welcome.
The limitation of Xbee is packet size:
*For Series 1 it is 100 bytes; Series 2 varies depending on firmware and
configuration, but is generally at least 80 bytes*
as taken from: http://code.google.com/p/xbee-arduino/wiki/DevelopersGuide
If the data you are going to send is less than that size, you are fine. If
more... you will need to layer your protocol with several packets per
transmit.
Generally the choice between Series 1 and Series 2 modules are based on the
architecture of the network. For simple 2 nodes (one remote and one PC),
Series 1 is good. Series 2 is required in the cases where you need much
more devices and peer-to-peer between them (at least from your initial
description, that does not seem to be the case). Also with Series 1 there
is easier way to do remote firmware upload to the Arduino (that is the PC
programs the remote device wireless). With Series 2 *I think* it is not
possible.
After you decided on the right series to use, your next step is to figure
out the distance you expect between devices. This will lead you to select
the module based on power of transmission. If power consumption is of any
issue (like the case of batter powered devices) then this might be more
complicated. Also, with Series 2 I know you can have repeaters setup
easily, while in Series 1 I am not so sure (you will have to read about
that).
One more subtle difference between the two series is the price.
Yours,
Zakie
